He could argue that the Elves give them a crash course in fighting. It could take just a mere decade or so. But I am fairly convinced that he’d agree that they should have some basic fighting skill, and know how to use a few weapons, at least through hunting (even if that isn’t exactly the same).I don’t agree that they atrophy while they’re in peacetime as the Professor suggests. If their skills atrophied, why would they take a position at the front lines if they’re going to be ill-prepared or useless? I have a problem with the House of Beor going to Nargothrond but it appears that the Professor is dead-set on it.
